i also have PTSD, which is healthier than i was a few years back, but still enough to make my Master nervous about playing with me. W/we took O/our time, and communication has been so important as said above. Sometimes a small miscommunication can bring me to tears because i say for example thought i wasn't going to be punished and was. i have found that there are times when W/we play that i need Him to kiss me so i can connect to Him and remember He loves me. If for whatever reason W/we have a busy few days with the kids and work i may need Him to spend some time gently touching me so i can slip back into feeling safely. i have found that i feel safer when "collared" so W/we moved into a 24/7 TPE kind of thing. There are moments the vestiges of past experience will surface for no reason at all, like flinching if He strokes my cheek but for the most part i feel safer with my Master than anyone on the planet. i hope it works out for you too!
